Project characteristics
Operation in extreme cold regions (Canada, Siberia, polar areas)
Or high ambient temperatures in tropical and desert climates
Ambient conditions strongly affecting cooling performance
Gelan solution
For cold climates, Gelan integrates internal air recirculation systems with positive and negative step auto-variable fans, allowing independent control of intake air temperature and preventing fluid clogging.
For hot and tropical climates, Gelan applies air humidification systems, including:
● Flow humidifiers
● High-pressure spray systems
● These systems can be integrated into new units or retrofitted to existing air fin coolers.
Value delivered
● Stable operation regardless of ambient extremes
● Extended operating envelope of air-cooled systems
● Adaptability to changing climate or process conditions
● Extended operating envelope of air-cooled systems
● Adaptability to changing climate or process conditions
Air fin coolers eliminate water consumption, reduce corrosion risk, and lower long-term operating costs while being environmentally friendly.
